<P>PROBLEM TO BE SOLVED: To provide a junction structure using a lag screw bolt, which has no need of working a long hollow hole to the lag screw bolt, can be configured such that only a junction component can be exchanged without replacing a joined member, has no apprehension in terms of long-term safety, and does not easily cause crack destruction of the joined member. <P>SOLUTION: First and second lag screw bolts 6 and 8 for which male screws are formed on an outer peripheral surface and female screws are formed on the inner peripheral surface of a hollow hole communicated with the opening of an end face are fixed to first and second members 2 and 4 so as to expose the opening. First and second metal fittings 10 and 20 are fixed to the first and second members 2 and 4 by utilizing the female screws of the first and second lag screw bolts 6 and 8 so that tensile force acts on the first and second members 2 and 4 through the freely turnably connected first and second metal fittings 10 and 20 and opposing surfaces 2t and 4t facing each other of the first and second members 2 and 4 are press-fixed to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
